In your 5.5 gallon nano reef tank, a good practice is to perform approximately a 1-gallon water change every week. This helps maintain stable water parameters and supports coral health.
When performing a water change, siphon detritus and vacuum the substrate to keep the tank clean. It’s also a good time to change the filter cartridge and prune back any overgrown corals or algae.
To reduce evaporation, use a tight-fitting glass lid and regularly top off the water with distilled or RO water. In your case, you may only experience a loss of about ¼ to ½ cup of water, making topping off manageable.
Feed a tiny pinch of slow-sinking pellets daily for your fish, and introduce frozen foods like Cyclopeeze approximately once a week. You can also use liquid foods like DT's every 2 to 3 days to enrich your aquarium.
Corals in your reef tank, especially types like Ricordea and zoanthids, benefit from occasional feeding of liquid foods and particulate matter such as Cyclopeeze, which offers nutrients they need to thrive.
A suitable lighting option is a 20" fixture with a 40W 'Smartpaq' bulb, which provides both 10,000k and 460nm actinic light. This will promote growth and coloration in corals and other marine life.
Yes, a heater is essential to maintain a stable temperature. In your setup, a 25W submersible heater works well for a 5.5 gallon aquarium, helping to keep the water at an appropriate temperature for your inhabitants.
Regular maintenance such as weekly water changes and using a high-quality filter will help. Monitoring specific gravity and using a refractometer ensures that salinity levels remain stable as well.
Beginner-friendly corals include soft corals like Ricordea, Zoanthids, and Xenia, which tend to be hardy and forgiving of newbie mistakes. They will flourish in your nano reef under the right conditions.
Yes, you can have a diverse mix of invertebrates such as hermit crabs, snails, and crabs. Just be mindful about compatibility, as some species may be more aggressive or territorial than others.
For a nano tank, the Green Banded Goby is an excellent choice as they are peaceful and small. Be cautious about stocking levels, as densely stocked tanks can lead to increased aggression and stress among inhabitants.
